Abstract
An improvement in the method of transporting viscous hydrocarbons through pipes is disclosed. Briefly, the method comprises adding water containing an effective amount of (a) an anionic alkyl polyether ethoxylated sulfate or (b) a combination of this material with an alcohol ether sulfate. The resulting oil-in-water dispersion has a lower viscosity and is more easily transported.
